Definitions

  • the present invention relates to a method for measuring blood pressure, and to a blood-pressure measuring device for carrying out the method.
  • Blood pressure is normally measured with the aid of a blood-pressure cuff or sleeve which is applied around the upper arm of the patient (or sometimes around the patient's thigh).
  • U.S. Pat. No. 3,812,844 teaches a blood pressure cuff incorporating automatic compensation of the measured values in dependence on variations in the diameter of the measurement object. This is effected by dividing the blood pressure cuff into a plurality of longitudinally extending sections, each of which is associated with a respective indicating range on the measuring device. This requires the use of a special blood pressure cuff in order to obtain a corrected measurment value, this value only being corrected with respect to the circumference of arms and not with respect to the remaining parameters aforementioned.
  • the pulse frequency of a patient at the time of measuring blood pressure will also influence the blood pressure value measured with the universal cuff.
  • the universal cuff tends to indicate an excessively high pressure value. This may depend, for instance, on the extent to which the heart is filled prior to blood being pumped therefrom. At high pulse rates, the heart is not completely filled, and consequently the heart beats will not be as powerful as heart beats at low pulse frequencies.
  • the true blood pressure value is exaggerated or overestimated, i.e. the pressure value read-off is somewhat higher than the true blood pressure value. This is probably due to the fact that the veins and arteries become stiffer with age.
  • the pressure level of the patient at the time of measuring blood pressure will also influence the blood pressure value measured by the universal cuff, wherein a low blood pressure results in depreciation of the true blood pressure, whereas a high pressure level results in exaggeration of the true blood pressure.
  • the limit for treatment of a patient for, e.g., hypertony, i.e. increased blood pressure, may depend on whether the patient has a lower pressure, i.e. a diastolic pressure, of 95 or 100.
  • a lower pressure i.e. a diastolic pressure
  • the present invention attempts to solve the aforesaid problems, by introducing corrections for the aforesaid systematic errors occurring when measuring blood pressure with an universal or unitary cuff, thereby to eliminate the error margin to the greatest possible extent.
  • the single Figure of the drawing illustrates a blood pressure cuff, by which is understood a conventional cuff with regard to its basic construction of casing, lining, and burr-fastener or VelcroR fastener.
  • the cuff 1 is provided with a manometer 3, in a conventional manner.
  • the cuff 1 is also connected to a pressure gauge 2 which sends a pressure value dependent on the pressure in the cuff 1 to a correction unit 4, which functions to correct the systematic errors contingent on variations in parameters characteristic of the patient concerned, i.e. age, sex, arm circumference, pulse frequency and pressure level occasion at which blood-pressure is measured.
  • the correction unit 4 is also connected to an infeed unit 6 and a display unit 8.
  • a device for measuring blood pressure in the home and without the assistance of a doctor can, for instance, be constructed in the above manner.
  • the pressure sensor 2 will send to the correction unit 4 a pressure-level value obtained from the cuff 1.
  • a pulse-frequency value obtained with the aid of a known oscillometric technique (not shown).
  • the correction unit 4 will automatically correct the pressure value sensed by the cuff in respect of those systematic errors dependent that are contingent on pulse frequency and pressure level at the moment of measuring blood pressure. This can be effected with the aid of regression coefficients.
  • the patient concerned then feeds in data concerning his/her age, sex and arm circumference manually with the aid of infeed unit 6, which converts this information into signals, which are then transmitted to the correction unit 4.
  • the correction unit 4 then functions to correct the blood pressure sensed by the cuff in respect of those systematic errors which are contingent on the patient's age, sex and arm circumference.
  • the arm circumference can be readily measured, with the aid of a "tape measure" mounted on the cuff, so as to enable the arm circumference to be read-off when the cuff is placed around the upper arm in a conventional manner.
  • the correction unit 4 then sends the corrected values to the display unit 8, where the true pressure values for the systolic and diastolic pressures are displayed in a respective display window.
  • the pulse frequency can also be displayed on a further display window provided on the display unit 8.
  • the present invention was tested by measuring the diastolic pressure of 50 people with the aid of the universal cuff (12 cm wide), with direct pressure measurement and with the inventive blood pressure measuring device.
  • the average value of the pressure values measured with the universal cuff was 84.3 mm Hg.
  • With direct pressure measurement (which is highly reliable) the average value was 76.6 mm Hg.
  • a mean value of 76.52 mm Hg was obtained.
  • measuring of blood pressure should be as exact as possible. This is achieved with the inventive blood-pressure measuring device.
  • the aforesaid trial also showed that individual deviations with respect to the aforesaid variables age, sex, arm circumference, pulse frequency and pressure level measured with the inventive blood-pressure measuring device in comparison with conventional blood-pressure measuring devices (using the universal cuff) were found to be in the region of 2-17 mm Hg.
  • FIG. 1 merely comprises an example of how the invention can be realized and is not limitive of the invention, the scope of which is defined in the following claims.
